Can you tell me a bit more about Overdrive? In laypersons language? Like, I'm guessing...you go to a website, pick the book you want, download something onto your comp, "borrow" the book to you compter, then download something else on your nook (overdrive program or whatever), then send it to your nook via usb cable? How do you get the access to "borrow" from a elibrary? Im I right in assuming Overdrive is a library? Sorry about the dumbness in my questions...
